Birck: Cleanroom Humidity - Fully Operational
by Hosler, Daniel A 26 Oct '23

26 Oct '23

Dear Birck Cleanroom Users, As of 7:30am this morning, the relative humidity within the cleanroom is back to full control and is within specifications. Please note relative humidity within the labs of Birck was not affected by this recent ultrapure water shutdown, and has maintained control throughout the duration. Thank you for your patience during this ultrapure water repair. Dan Hosler Senior Research Facility Planning Engineer Birck Nanotechnology Center | Room 1120 Office: 765.496.3883 | Email: dhosler(a)purdue.edu

NOTICE - Failure of the Ultrapure Water System and Cleanroom Humidity Control
by Voorhis, Mark L. 21 Oct '23

21 Oct '23

Dear BNC User, Tonight at 3:15AM the ultrapure water system has failed and shut down. There is no ultra-pure water flow in the building currently. As a result, the humidity in our clean room is completely out of control and our humidification system is down since it's dependent on ultrapure water to operate. Once ultrapure water is restored it will take 24 to 48 hours for the cleanroom clean steam generators system to heat up and stabilize before we can start generating steam for the cleanroom humidification system. Ron Reger and his team are currently addressing the ultrapure water issue. Regards, Mark Voorhis Building Manager Purdue University Birck Nanotechnology Center Office: (765) 494-3036

All BNC Users - The preventive maintenance closure of the Birck Nanotechnology Facility has been completed successfully. The cleanroom and laboratories are now open for research. Some research equipment is still down for maintenance or is in the process of being started back up. Please check iLabs for individual equipment status. Thank you for your patience and understanding during this important preventive-maintenance time. Special Notice for Future Planning With the approval of the CHIPS Act Project, the Birck Nanotechnology cleanroom will undergo major utility infrastructure modification that will extend our normal preventive maintenance closure in 2024 and 2025. We are currently in the design phase and more details will be communicated as soon as possible. Future PM Dates * Week of April 29, 2024 * Week of Oct 14, 2024 * Week of May 5, 2025 Best Regards, Greg LaOrange Facility Engineer Purdue University Birck Nanotechnology Office: Phone 765-496-8329 Cell: Phone 574-870-7721

Loss of Campus Steam
by Voorhis, Mark L. 06 Oct '23

06 Oct '23

All, We have just received multiple building alarms that the campus has lost all steam pressure. This will have a negative impact on the entire building ambient controls (colder temperature and lower humidity) involving all labs and cleanroom operations. The Director of Energy and Utilities just texted me and it will be several hours before the plant will recover. Please plan accordingly to protect your research. I will keep you posted as conditions change. Mark Voorhis Building Manager Purdue University Birck Nanotechnology Center Office: (765) 494-3036
